Menu direction

You can change the direction of the menu with direction = :up or direction = :down. By default, the direction is determined automatically to avoid cutoff at the figure boundaries.

using GLMakie

fig = Figure()

menu = Menu(fig[1, 1], options = ["A", "B", "C"])
menu2 = Menu(fig[3, 1], options = ["A", "B", "C"])

menu.is_open = true
menu2.is_open = true
